Courier Lin Mo joins a local delivery station and faces harassment from the manager for standing up for his frontline colleagues' rights. Familiar with industry rules and relevant laws, he successfully resolves the injustice through a complaint and goes on to crack a series of valuable parcel-swapping cases. He confronts vicious competition from rival companies, including undercutting prices and covert sabotage. After being deliberately suppressed by headquarters, Lin Mo teams up with his longtime colleagues to establish an independent delivery brand. By chance, he uncovers the history of his father's company being stripped of its equity, gathers complete evidence, and regains control of the group. Once in power, he improves welfare benefits for frontline workers and builds rural logistics networks to support farmers, always staying true to the original spirit of service while balancing industry responsibility with human warmth.
